ENGINE AND RADIATOR HEATER.

To all who-m 2'23 may concern Be it known that I, JOHN R. WESTON, a citizen of the United States, residing at Du- .buque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Engine and Radiator Heaters; and I do declare the following to be a full, clearfand exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the-same. V

This invention f relates to an improved heater for use in connection with the engine and radiator of an automobile or other motor driven vehicle, and. one object of the invention is to provide a heater in which the burner or other source of heat may be mounted in a housing, the burner having a discharge or draft pipe extending through the roof of the housing andan auxiliary roof orhood being placed above the housing to'provide an airspace through which air may pass and into a pipe inclosing the extended end portion of the discharge pipe topermit the products of combustion to form a suction which will draw the air into the air pipe.

, Another object of the invention is to so construct this heater that the air which is drawn into the pipe from between the auxiliaryroott' or hood and the [roof of the housing may be. thoroughly heated and the warm air additionally heated by being ,mixed with products of combustion'passing out through the extended end of the discharge pipe.

Another object of the invention is to so construct this heater that the burner may be provided with a fuel reservoir having supply pipe leading through the housing and terminating 1n-ameasur1ng receptacle in the form of a funnel thereby permitting a desired quantity of fuel to be delivered to the fuel reservoir when a valve controlling passage of the fuel through the supply pipe is opened.

Another object of the invention is to so construct this heater that a storage tank may be provided with an outlet pipe terminating above the funnel or measuring receptacle thus permitting the liquid fuel to be delivered to the receptacle and a meas-. ured quantity thereof then delivered to the reservoir of the burner,

Specification of Letters Patent.

Application filed December 16, 1920. Serial No. 431,223.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view partially in section and partially in elevation and showing the'device in use.

VFig. 2 is a perspective view of the hood which fits over the motor.

This {heater is provided with a housing 1 having a doorway 2 for permitting access tothe interior of the housing, a door or other suitable closure 3 being provided so that the doorway may be closed when the heater is in operation. Openings 1" are provided in the walls of the housing so that air may pass into the housing to supply the necessary air for the liquid fuel burnerd positioned in the housing and resting upon the flooring thereof. This burner 4 is'of a conventional construction and is provided with the usual reservoir 5 for holding the fuel. A supply pipe 6 extends from the reservoir 5 t Trough one of the side walls of the housing and has its outer end portion extending upwardly and connected with a measuring cup 7 which constitutes a funnel for the pipe 6.. A. valve 8 is provided so that a desired quantity of the liquid fuel may be fed into the measuring cup and the valve then opened and the fuel permitted to pass through the pipe 6 into the reservoir 5 of the burner. A storage tank 9 is sup ported upon a suitable shelf or other sup port 10 and is provided with a valve (3011-, trolled outlet 11 which terminates above the measuring cup 7 thus permitting the fuel to be fed into thermeasuring cup by simply opening the valve of the pipe 11, the valve 8 being closed. r

The burner 4 is provided with a discharge pipe .12 which forms a chimney for the burner. This discharge pipe extends up through the roof of the housing and extends into a heated air pipe 13 which is provided at its lower end with a flaring hood 14 which forms an auxiliary roof for the housing and is supported in spaced relation to the roof of the housing thus providing space through which air may pass in order to enter the pipe 13 through its lower end. It will thus be seen that this air will be heated before it enters the pipe 13 to its passage through the space between the hood 14 and the roof of the housing. It will be further noted that the passage of the products of combustion through the pipe 13 from the discharge pipe or chimney 12 will cause a suction in the pipe 13 and tend to draw the air into the outer pipe through the lower end thereof. This pipe 13 is provided with an elbow 15 so that the hotair pipe may be extended to the point where the automobile or other motor vehicle is usually placed when not in use. A hood 16 has been provided at the outer or free end of the hot air pipe 13 and this hood which is provided with side walls and a roof as shown, is open at one end and at its second end is provided with a head 17 Which tapers to and is connected with the pipe 13. It will thus be seen that the hood 16 may be placed to inclose the motor and radiator of an automobile and the heated air from the pipe 13 will pass into this hood and will serve to keep the motor and radiator warm and prevent freezing of the water in the radiator and further prevent the engine frombecoming cold. When a motor has been standing idle all night and has become chilled, it is diflicult to start the motor and it is to prevent the motor from becoming cold and to prevent freezing of the water in the radiator that this device has been provided. The pipe 8 may be of a rigid construction and the automobile driven into the proper position to place the motor and radiator within the hood 16 or the pipe 13 may be of of a .i'lexible construction and properly placed upon the motor and radiator after the automobile has been brought to a stop.

There has thus been provided a device of the character described which will operate very efiiciently and will supply heated air to the motor in a suflicient quantity to prevent freezing of the water and prevent the motor from becoming chilled. There has further been provided a heater so constructed that when the device is in operation and thereservoir 5 needs refilling, it is not necessary to open the housing and remove the burner, but it is only necessary to fill the measuring cup and then open the valve 8 and permit the fuel to pass down through pipe 6 into the reservoir.

What is claimed is: 1

1. A heating device comprising a housing having a roof of heat conducting material,

an auxiliary roof for said housing supported above the roof of the housing to provide an air passage between the housing roof and auxiliary roof, a heater in the housing. having a discharge pipe extending through the roof of the housing in air-tight engagement with the housing roof and through an enlarged opening in the auxiliary roof, and an air conducting pipe extending from the opening in the auxiliary roof with the discharge pipe of said stove extending partially through the air pipe, in spaced relation to the same.

2. A heating device comprising a housing having a roof of heat conducting material,-

an auxiliary roof spaced above the roof of the housing to provide an air passage between the housing and auxiliary roof, a heater in the housing having a discharge pipe extending through the roof ofthe housing and through an opening in the auxiliary roof and having air-tight engagement with the housing roof, an air conducting pipe ex tending from the opening in the auxiliary roof in spaced relation to the discharge pipe and inclosing the extended portion of said discharge pipe, and a hood for inclosing the article to be heated communicating with said outlet opening, a heater in the housing having a discharge pipe extending through the housing roof and the outlet opening of the auxiliary roof and having air-tight engagement with the housing roof, an air pipe extending from the air outlet opening, and po sitioned about the discharge pipe in spaced relation to the same and a hood carried by the pipe for inclosing a motor and radiator. 4t. The structure of claim 3 having the motor and radiator inclosin hood provided with side walls and a roo one endof the hood being open and the second provided with -"a tapering head communicating with the air pipe.

In testimony whereof I have hereunto set my hand.
